B&W N803 versus Dynaudio Contour 3.4

I am in the final stages of making a speaker decision. It has been approximately 15 years since I last bought speakers and would like to get a decent set around $5000 which I plan to keep for a few years. I am down to the B&W N803's and Dynaudio Contour 3.4's. Honestly, I cannot decide. I like both sets. This is a great forum with very informed individuals and I would like your input. Which of these two do you like best and why? Why would I want to purchase one set over the other? I am putting together a combo HT and stereo system in the same room. I will use them about 60-40, HT versus music. If it matters my room is app. 19X20 with 16ft ceilings. Thanks in advance for your input.
